Abstract
(EN)
The present invention is a method for producing an optically active 2-methylpiperazine, the method comprising: adding a solvent to a solution of an optically active 2-methylpiperazine and subjecting the same to solvent displacement; and then crystallizing the same, to obtain crystals of the optically active 2-methylpiperazine. With this method for producing an optically active 2-methylpiperazine, the optically active 2-methylpiperazine is further refined at the time of crystallization, and thus, a high-quality optically active 2-methylpiperazine can be obtained.

La présente invention concerne un procédé de production de 2-méthylpipérazine optiquement active, le procédé comprenant : l'ajout d'un solvant à une solution de 2-méthylpipérazine optiquement active et la soumission de celle-ci à un déplacement de solvant ; puis la cristallisation de celle-ci, afin d'obtenir des cristaux de la 2-méthylpipérazine optiquement active. Avec ce procédé de production d'une 2-méthylpipérazine optiquement active, la 2-méthylpipérazine optiquement active est davantage raffinée au moment de la cristallisation, et ainsi, un 2-méthylpipérazine optiquement active de grande qualité peut être obtenue.
